My gelding is boarded on a small private
farm. Four horses and one small pony on six acres. They are usually
on pasture about 8-10 hours daily and otherwise in a dirt/mud paddock.
Because of such small acreage, the new vet
has recommended that all the horses be on a daily wormer, with twice-yearly
ivermectin and a once-yearly double dose of Strongid paste for
tapes.
I know that a while back there was some discussion
on Ridecamp that daily wormers were not a good idea for distance
horses. What's the current poop (pun intended) on this issue? Any
hard data available regarding daily wormer and hard-working horses?
